When I was still working in Turkeys, we had to start coming at night time to select kulls out, de-beak, or move the birds to avoid them getting to hot and dying on us.
They saying that they only have 24 hours left on the lease yet every time one of them find a nugget they all have to stop and go look at it. Dont stop there will be plenty of time to look at them all when you are done.
I have been watching the gold hunting shows for several years. I have never understood why the insist on working in the heat of the day. Put a few more floods on the loader to lighting things up (sorry couldn't resist) Also the bugs aren't quite the problem
